顺序语法

Question

按ASC排序的正确语法是什么

?

错误1名称"ASC"在当前上下文中不存在

 public IEnumerable<DTO> GetGrid(String ShipNumber)
    {
        try
        {
            ORepository rep = new ORepository();
            var query = rep.GetAll()
                .Where(x => x.SHIP == ShipNumber)
                .Orderby (x.City ASC)
                .Select(g => new DTO
                {
                    CUSTOMER_NAME = g.CUSTOMER_NAME,
                    CITY = g.CITY,
                    SHIP = g.SHIP,
                });
            return query;

Answer 1

• .OrderBy(x => x.City)为升序
• .OrderByDescending(x => x.City)按降序排列

Answer 2

在使用Distinct时使用此查询。

var result = ctx.tblCity.AsNoTracking()
 .Where(s => s.City== "Chennai")                                 
 .Select(s => new Area { Name = s.AreaName})                                 
 .Distinct().OrderBy(s => s.Name).ToList();

Answer 3

IEnumerable<t_HomeRequets> homeRequets = cnx.t_HomeRequets
    .Where(x => x.HomeRequestId > DeletedId && x.BuildingId== BuildingId)
    .OrderByDescending(s => s.HomeRequestId)
    .AsEnumerable<t_HomeRequets>();

输出IEnumerable集合您可以使用var或任何类型
